3DExport – buy & sell 3D models. There’s an excellent variety of tens of thousands of models organized by categories. 3D printing models included too.
This one actually sent me into a lot of thinking (which is still not complete). On one hand, I am very anti-gun. On the other, I am very pro-Open Source. I do agree with the point Cody raises about there being no more politics or politicians, just a pseudo-selection between the candidates who protect the same class of people. Also, Nick’s saying that 3D printing technology is getting better and cheaper fast, and that law has always been way behind technology – this all makes 3D gun printing a complicated issue.
